Electric potential of noncunducting arcs

[AMMax]

Homework Statement

There are three nonconducting arcs of radius R=8.5cm. The carges on these are as follows: q1= 4.52pC, q2= -2q1, q3= 3q1. With V=0 at infinity, what is the net electric potential of the arcs at the common center of curvature?

Homework Equations

used Vnet= k(q1/r+q2/r+q3/r)

The Attempt at a Solution

Used that formula and came up with 1.063x10^-4 as an answer. This just seemed really easy and I am wondering if I missed something.

I also wanted to check if my formula usage was correct.

Hello,

Your usage of the formula is correct. However, it is always a good idea to double check your work and make sure you didn't miss any steps. It is possible that you may have missed a negative sign or a decimal point, which may have resulted in the seemingly easy answer.

In addition, it is important to state the units for your answer. The units for electric potential are volts (V), so your final answer should be 1.063x10^-4 V.

It is also helpful to write out all the given values and their corresponding units to ensure that you are using the correct values in your formula.

Overall, your approach is correct and your answer may be correct, but it is always a good idea to double check your work and be thorough in your calculations. Good luck with your studies!
